Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Bevacizumab beyond progression has been proven to be safe in the community setting (BRiTE) and in the post-marketing study (BEAT), and confirmed its efficacy and safety in the first line with all regimens of chemotherapy. A total of 1,953 patients were treated in BRiTE. At median follow-up of 17.5 mo, there were 1,369 1st PD and 839 deaths. Among patients with 1st PD, 65.2% received any 2nd-line chemotherapy, 34.8% received cetuximab, and 53.8% received BBP. In a multivariate analysis, Bevacizumab beyond first progression and exposure to any 2nd-line chemotherapy were independently associated with increased overall survival (both p \< 0.0001). Bevacizumab beyond progression appears to be associated with longer overall in BRiTE.

The investigators planned a prospective study to prove this phenomenon of bevacizumab beyond progression.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Patients should have been treated with bevacizumab plus chemotherapy as a 1st line treatment, and after 1st progression, these patients will be accrued in this study of bevacizumab plus chemotherapy as a 2nd line treatment, and the combined chemotherapy will be chosen by physician's decision in consider with previous chemotherapy.
